We report the clinicopathologic findings in a case of coexistent glottic granular cell tumor and subglottic spindle cell carcinoma. There is no evidence in this case that suggests malignant transition of the granular cell tumor to malignant tumor. To our knowledge, this is the first report of synchronous granular cell tumor and subglottic spindle cell carcinoma.
